Macbook Air as a second monitor
Is there a way to use a Macbook Air as a second monitor? I know I can use a iMac to extend the Air's screen using 'Command' + 'F2' but I would like to do the opposite and use the Air to extend my iMac's screen.
There were some old responses to this question referring to a solution using "ScreenRecycler". However, the site looks quite dated and I'm weary of using a program that may no longer supported.
